Specification of Letters Patent. Patented June 13, 1911.

Application filed November 20, 1903. Serial No. 182,000.

To all whom it may concern.'

Be it known that l, WILLIAM H. TROUT, a citizen of the United States,residing at Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements in Sawmill.Set-VVorks, of which the following is a specification.

My present invention relates to impro'vement.. v.in saw-mi1l carriages,the construction and 'advantages of which will be hereinafter setfort-h, rference being had to the annexed drawings, wherein Figure l isa side elevation of a saw-mill carriage, showing my improved set-worksand/the means employed for impartingI motion to the setting andreced-ing drums; Fig. 2 a/similar view on an enlarged scale; Fig. 3 atop plan view of the operating portions of the set-works, the stand orcolumn being broken away to more clearly show the parts beneath; Fig. 4a transverse vertical scctional View taken on the line 4 4 offFig. l;Fig. 5 a top plan View of the upper portion of the stand or column,showing the scales and the setting lever; Fig. 6 a horizontal sectionalview, taken on the line 4-4 of Fig. 4; Fig. 7, avertical sectional viewtaken on the line 6-6 of Fig. 6; Fig. 8 a detail view showingthe leveremployed for shifting the friction driving dru-n or pulley; and F ig. 9a detail perspective view, showing the means employed for lookin thesetting lever against rebounding action. Fig. 10 is a scctional `viewtaken on line 10, 10, Fig. 4.

The principal object of my invention is to provide a simple andefficient set-works in which the degree of movement to he imparted tothe knees can be readily determined and. effected without overthrowing,breaking, or damaging the mechanism. even though the operator fail todiscngage the parts from thevconstantly rotating friction drum' orulley.`

A furt er object of the invention is to construct the mechanism so thatthe set-shaft and knees may bel worked .by hand, should Ehe] power whichdrives the operating drum The invention will be best understood uponreference to the annexed drawings, wherein- A denotes the saw-millcarriage, which may be propelled in any suitable manner.

Mounted upon carriage A is a shaft B, Said shaft carrying a friction.driving drum or pulley C, preferably formed of paper. Upon the' outerend .of shaft B is mounted a shcave-whcel D. A second shaft E islikewise mounted upon the carriage, said Shaft being parallel withshaft. B, and carrying a larger drum or pulley F. A sheave-Wheel G iscarried at the outer end of shaft E, the sheaves D and Gr being in linewith each other and in the same vertical plane with largersheave-w'heels H and 'f adjustably secured to the frame-work of themill. An endless rope or band J passes about the sheaves (i, D, H andand about similar sheaves K and L, which, as shown in Fig. l, arelikewise secured to the frame-work of the mill. The shaft upon whichsheave-l whecl l( is secured also carries a pulley. M, about whichpasses a belt N, said belt serving to impart motion to pulley M and tosheavc K. By this construction motion will be imparted to rope J to thesheaves G and D, and consequently to the paper friction drums() and F,said drums rotating ,in the directions indicated by the arrows in Figs.2 and 3.

A shaft O, carrying a friction drum P, preferably of iron, is mountedintermediate the shafts B and E, the outer end of shaft O beingsupported in an eccentric or sliding box or hearing Q, so that drum Pmaybe thrown into contact with either drum C or l4`. Box Q is providedwith an upwardlyextending arm R. to the end of which is attached a rodS, the opposite end of said rod being fastened to a bell-crank lever T,which has its opposite end secured to a second rod U, which in turn isconnected to the lower end of an operating lever V`,see Figs. 3 and 8.As will be seen more particularly upon reference to Figs. Q, 3 and 8 ofthe drawings, lever V is fulcrumcd or pivoted in a stand W, which isprovided with oppositely-extending arms X. Mounted in the ends of saidarms, and free to move therethrough, are rods or bolts Y, the innerrounded ends of which bearagainst the opposite sides of lever V. Bolts Yare held inwardly by coiled springs ZA, one of vvhich is placed aroundeach bolt. The normal position oflever V is that shown in Fig. 8, inwhich position friction drinn P Will be held out of contact with eitherthe setting drum C or the receding drum F. Springs Z will always tend tobring lever V back to its medial position, and as a consequence willWithdraw the intermediate drum P from contact With either the setting orthe receding drum, as the case may be. j

In order to reduce to `a minimum the amount of transmission means whichit is necessary to have stopped at the time of setting, and also toprovide an easily accessible means for localizing Wear of frictiontrans` mission and make same adjustable, a second friction device isused located between the point of application of the actuating frictionmeans and the set shaft and so located as to Ybe freely accessible andreadily renewable.

Keyed to shaft O, near its inner end, is a pinion a, which in turnmeshes with a spur gear or pinion 17; loosely mounted upon a hub c,which in turn is keyed fast to a shaft 6l,

andin line with shaft 'vided with a beveled face against said shaft bypreference being placed above i O. Pinion b is prowhich works a paper orsimilar friction member e. Said friction member may be forced inwardlyby manipulation of the nuts f and g, which asbest shown in Figs. 3 and 4are provided with extended arms for the purpose of permitting theoperator to adjust them With his foot. Shaft ci haskeyed to it a bevelpinion i', which meshes With a bevel Wheel 7s, which meshes with apinion secured upon the set-shaft proper. The bevel Wheel is mounted-upon a'shaft m, mounted to rotate within a column or stand n. Theset-shaft,

as will be readily understood by those skilled in the art, may beconnected up in any approved manner to impart the Irequisite motion toset and recede the knees. Shaft m has secured to it' a toothed Wheel 4o,said wheel rotating with the shaft at all times. An arm or )bracket 77is pivotally mounted upon shaft fait, the members thereof passing to theupper and lower sides of Wheel o, as best shown in Fig. 4. A block g,provided with teeth which correspond to the teeth formed in the verticalor outer face of Wheel Ia, is carried by arm or bracket p, said blockbeing designed to be moved inwardly to permit its teeth and the teeth ofWheel 0 to lock together when desired. Block g is moved inwardly oroutwardly by means ofa lever 7' fulcrumed in arm or bracket p andpivotally connected to said block near its ldiver end. A link s formsthe support for the upper end lof the block, and insures a parallelmovement of the face of the block with the teeth formed upon Wheel 0. Aspring-actuated locking pin t Fig. 10 is carried by block g, the bevelednose of said pin entering recesses or depressions formed inI the innerface of the arm 'or bracket p, and thus serving to hold the block in oneor the other of its positions.

A plate or disku, Fig. 4 provided with a Adownwardly depending rim orskirt o, is

journaled upon the shaft m beloiv- Wheel o and arm or bracket p. In therim of said disk is mounted a series of pins w, the outerends of whichnormally stand fiush with the outerface of the rim or skirt v Theconstruction of the pins is such that any one of'them may be prot'ru-dedbeyond the periphery of ,the skirt, as shown in Fig. 6, to form a stopor abutment'for the downwardly-projecting finger or member a: Fig. 4formed' upon 4arm or bracket p, said pins being held in their adjustedpositions by means of springs y, see Fig. 6. The location y of the pinsaround the periphery of disk u, with relation to the fixed stop orabutment .e formed upon column n, will be such as to represent thestandard thicknesses of lumber; as, for instance, the first pin willindii cate a distance of one-half of an inch from the saw, the nextthreefourthsof an inch, and so on around the disk to a distance of, say,four inches or that indicated by the pin shown protruded in Fig. 6.

j Plate or disk u is formed at one side with a segmental member A', Fig.7 the under face of Which is provided with a series of teeth B. A leverC is pivotally connected D', the inner end of said which movement willeffect a relative movement of plate or disk u with reference to the.

fixed abutment e.

Rotatably mounted upon the upper end of the shaft m' is 'an index plateor dial G,

rovided with a scale of the knees from the saw, and also with the usuallumber scales. This index plate or dial works past a fixed pointer Hsecured to the stand n. Rotary'motion is imparted to said index plate ordial through pinion I, keyed to the shaft m, and intermediate idlergears J', K, the Alatter in turn meshing With the teeth formed upon theinner face of the deendin(r skirt or rim of said dial. P e

As will be seen upon reference to 2,

to indicate the distance.

f \wheel and bevel pinion j.

3 and 4, the upper end ofshaft m, is squared, as is also the outer endof shaft 4O.' This is done to permit a crank or lever to be applied tosaid shafts to impart motion thereto, in order to edect the setting orrecedingl of the knees in case the power mechanism should becomevdisabled.

The relative size of the transmitting pinions, as for example, the sizeof the pinions a and 5, may be varied according to the character ofv theWork.

In order to prevent any rebound of the parts when operating upon heavylumber, 4or with a large carriage, I employ a lockingpawl for thetoothed wheel o, best shown in Figs. 4,' 5 and 9. Mounted in the standn, adjacent to the toothed wheel 0 and parallel with the outerfacethereof, is a. shaft A2, carrying a pawl B2. A handle or lever C2 issecured to the upper end of the shaft, while a coiled or volute springD2 is attached at one end to the frame and at the opposite end to theshaft A2, said spring serving to hold the pawl in contact with the teethof the wheel o, and to prevent retrograde movement thereof. When it isdesired to use the setting mechanism without employing the pawl, thehandle or lever C2 may be drawn around lover the free end of a springwhich issecured to the column a and stands in line with the under faceof the handle, as is best illustrated in Figs. 5 and 9.

The operation of the apparatus .is as follows: Assuming 'that it bedesired to cut a Ll--inch plank or slab, the pin w located at theindication 4 (Figs. 5 and 6) is protruded outwardly, and the setting armor bracket p is brought around until the projection a; thereon comesinto contact with pin w. The handle of lever 'l' is then drawn outwardlyto force the teeth 4of block y into engagement with the teeth vupon thewheel or disk o. The operator will. then manipulate handle V, by whichfriction drum P will be shifted into contact with the setting drum C,and as a consequence motion will be imparted to said friction drum,which in turn will impart it to the set-shaft through shaft O, pinion a,spur gear o, friction member c, shaft d, bevel pinion z', bevel At thesame time motion willl be imparted to Ashaft m through gear 1, wheel obeing rotated and carrying with it the setting arm or bracket p. yhismotion continues until said arm comeslinto contact with the fixedabutment e, which by preference will be provided with a lrubber face orcushion. Contact of the setlfing arm or bracket with said fixed abutmzntwill prevent further rotation of sha-ft and owing to the directconnection of said shaft with the set-shaft Z through the gears y' and7c, rotation of shaft Z' Will cease and the knees will be brought torest when the log has been advanced four inches. Should the operatorfail to release lever V, and permit springs Y to act and thus to throwfriction drum P to its normal position intermediate drums C and F, noA

above or slightly below 4 inches, Vlever C" will be manipulated to shiftplate or disk u with relation to the xedabutment, either to increase orto diminish the distance, as desired. In this manner, it will be seen,the thickness of the lumber turned out'may be varied at the will of theoperator. When it is desired to recede'the knees, it is simply necessaryto shift lever V in such direction as to throw the intermediate frictiondrum P into contact with the relatively large receding drum F, theoperator holding said lever until 4the knees have been fully rev ceded,or receded the desired distance. At such timeslocking block g will bethrown by the operator to such position `that its teeth willI be out ofcontact with the teeth of wheel o, permitting said wheel to rotateindependently thereof.

As will be noted, the friction drums are all mounted upon the carriage,and motion is imparted to the setting and receding drums by a simplerope-drive.

Having thus described my invention, what I claim is:

l. A saw mill carriage, means carried by the carriage including asetting drum, a receding drum, a drum intermediate the setting and thereceding drums, a shiftable support for the intermediate drum, means forshifting the support, a set-shaft and a power transmission meansintermediate the set-shaft and the intermediate drum, including anadjustable friction connection.
